Notes from the Arnold Arboretum 



The Liliu-s are uow iu full bloom and form the centre 

 of attraction at the Arboretum. How much tlie beau- 

 tiful display is appreciated by the public is shown by 

 the great numbers of visitors who are coming daily to 

 the Arboretum, particularly last Saturday and Sunday 

 afternoon the driveway and the paths near the Lilacs 

 were literally thronged with visitors afoot and in car- 

 riages. In the last issue the earliest varieties were 

 noted and now, as all the varieties are in bloom, though 

 the earlier are nearly past their prime, some of the best 

 of all colors may be noted. Among the whites may be 

 mentioned Marie Legraye with large panicles, one of 

 the best single whites, early like Alha major and Vir- 

 ginalis, Noisettiana, Madame Casimir Perier, one of the 

 best double whites, Madame Lemoine, double-flowered, 

 late. Among the blue, lilac or pink varieties we note 

 Bleuatre, almost pure pale blue, the best of the blue 

 varieties, Coerulea superha, bluish lilac, very free-flow- 

 ering, Eouen, blue lilac, President Grevy, large panicles 

 of blue lilac double flowers, E. Lemoine, lilac, double- 

 flowered, Gelieimrat Heyder, light lilac, free-flowering, 

 and the similar Eckeholm, President Carnot, pale lilac, 

 double, late, Pyramidalis, lilac, dotible flowers in very 

 large panicles, Maxinie Cornu, lilac, large panicles of 

 double flowers, Beranger, dark lilac flowers in large pan- 

 icles, late, Alphonse Lavalle, pink lilac, free-flowering, 

 Croix de Brahy, pink lilac, early, Macrostachya, large 

 panicles of light pink flowers, Fuerst Lichtenstein, pale 

 pink lilac, free-flowering, early, Marechal de Bassom- 

 pierre, double pinkish lilac flowers in large panicles, 

 Comie de Kerchove, similar to the preceding, Gloire de 

 Moxilins, pink flowers, one of the best pinks. Of the 

 red and purple varieties the following are some of the 

 best : Congo, dark purple, large flowers in dense, some- 

 what nodding panicles, late, Andenl-en an L. Spaeth 

 (Souvenir de Louis Spaeth), dark purple, one of the 

 darkest, late, Charles Joly, dark purple double flowers, 

 the darkest of the double varieties, late, Philemon, dark 

 purple, late. President Massart, purple, late, Charles X. 

 (Caroli), purple lilac, Geheimrat Singelmann, purplish 

 lilac, large panicles, Marie Kreuter, purplish lilac, Aline 

 Mocqueris, dark red. Rubra insignis, purplish red. 

 Professor Sargent, purple lilac. Of the Persian Lilacs 

 the red Syringa chinensis var. rubra is perhaps the best. 

 The Lilacs of the Persica-grortp should never be planted 

 together with varieties of the Vulgaris-group, as the 

 two are too different in habit and the former with their 

 spreading slender branches bearing nodding broad pan- 

 icles would look out of place between the rather stiff 

 upright Vulgaris-varieties. The single-flowered varie- 

 ties are the best for general planting, they are more 

 free-flowering and have not the disadvantage of the 

 double-flowered forms that the faded individual flowers 

 do not fall off, but remain on the panicle which gives 

 the shrubs a very unsightly appearance, if the panicles 

 are not removed. 



Besides the Lilacs one of the showiest trees is Cornus 

 florida, the Flowering Dogwood, now covered with its 

 large white blossoms, but still more beautiful is its red 

 variety, C. florida var. rubra, with bright pink flowers; 

 its color effect in the landscape is about the same as that 

 of the Red-bud, but the pink of the former is purer, 

 more like that of the Peach; there are many fine trees 

 of it in the shrubberies around the Jamaica Pond. 

 Another striking tree is the Snowdrop-tree, Hatesia 

 tetraptera (Mohrodendron carolinum) covered now with 

 its numerous bell-shaped white flowers which unfortu- 

 nately do not last very long. 



The flowering crab-apples take now their leave with 

 Mains coronaria, the Fragrant Crab, and M. ioensis, the 

 Iowa Crab, both very beautiful with their pink, fragrant 

 flowers between the young foliage. Also Bechtels Crab, 

 M. ioensis var. plena, comes in for much admiration in 

 account of its' clusters of large double flowers looking 

 like bunches of little pink Eoses. 



Most of the Bush Honeysuckles are in bloom. Loni- 

 cera tatarica with its varieties ranging in color from 

 pure white to red and L. bella and L. notha, its hybrids 

 with L. Morrowii and L. Ruprechtiana, which show the 

 same variation in the color of their flowers, are now 

 very attractive. A handsome species is L. Morrowii 

 with pure white flowers changing to yellowish in fad- 

 ing ; it is a rather low spreading bush of dense habit and 

 keeps its scarlet fruits and its dark dull green foliage 

 unchanged until late in fall; this advantage is also 

 shown by the above named hybrids, while L. tatarica is 

 apt to become unsightly earlier in fall. Lonicera mtis- 

 caviensis is a hybrid of L. Ruprechtiana and L. Mor- 

 rowii, very similar to the latter, but of more upright 

 habit. A striking variety of the western Lonicera in- 

 volucrata with pale yellow rather insignificant flowers 

 is L. involucrata var. serotina which has yellow flowers 

 tinged with scarlet resembling in color and shape 

 much those of Manettia bicolor. A graceful little shrub 

 is L. tangutica with small but numerous pendulous pink- 

 ish white flowers and L. syringantha with upright pink- 

 ish white flowers; handsomer than the latter is its va- 

 riety L. syringantha var. Wolfii with flowers of a deep 

 lilac color and of a delicious fragrance reminding of 

 Hyacinths. Both species are of recent introduction 

 from eastern Siberia. 



Of the many other shrubs which are flowering may be 

 mentioned Primus maritima, the last of the American 

 plums to bloom. Spiraea Vanhouttei Deutzia purviflora 

 and D. Lemoinei with large clusters of pure white flow- 

 ers, Rhodotypus tetrapctala (E. kerriodes) with large 

 white flowers at the end of the branches, Xanthoceras 

 sorbifolia with numerous upright spikes of delicate white 

 flowers marked yellow and red. Viburnum prunifolium, 

 Kcrria japonica with yellow single and double flowers, 

 several species of Berberis with their showy golden 

 racemes, and species of Ribes.
